Thursday’s Republican primary in Smithtown saw an incumbent fall to the bottom of the pack in the town board race, but only by a slim margin.

Councilman Bob Creighton (R) came in third out of three candidates seeking the Republican line in November’s general election. The other two, incumbent Councilman Ed Wehrheim (R) and challenger Lisa M. Inzerillo came in first and second, respectively, all but assuring them Republican spots, according to unofficial Suffolk County Board of Elections results.

By Friday morning, Wehrheim had collected 40.49 percent of the vote — 1,673 total votes — and Inzerillo earned 31.27 percent, or 1,292 total votes. Creighton came in close behind Inzerillo with 27.81 percent — 1,149 votes.

Creighton had focused much of his primary bid on development in Smithtown that he said could attract new business to the community. He has served on the Smithtown Town Board since 2008 and has been a longtime ally of Wehrheim, often aligning with him in critical votes put before the board over recent years.

“There are still some 200-odd absentee ballots to count, but I have no illusions about that,” Creighton said. “I lost — period.”

Creighton said he attributed part of the loss to low voter turnout, with just about seven percent of Smithtown Republicans hitting the polls. The councilman also said he had full intentions of still running on the Independent, Conservative and Reform party lines come November, whether or not absentee ballots salvage his primary bid later next week.

Wehrheim has been on the board since 2003 and said in a previous interview that he would like to use another term to work on funding more projects to revitalize Smithtown’s downtown area. In a phone interview, the councilman said torrential downpours throughout the voting hours on Thursday may have had an impact on voter turnout, which was slightly lower than the average primary.

“I am very pleased with my position as number-one in the race, but I do believe the weather certainly had an affect on the voter turnout,” he said. “The board, as of late, is fairly divided, but I have a long tenure with the town and I will continue to do what I’ve always done. I will go in there, and work on behalf of the Smithtown resident.”

Inzerillo, a business owner from Kings Park, focused her campaign on making Smithtown’s downtown business district more vibrant. She declared victory following Thursday’s vote in a statement, looking forward to discussing the town’s most pressing issues.

“This grassroots campaign, fueled by family and friends, has inspired and humbled me and I am ready to represent the Republican Party in November,” she said.

Both Creighton’s and Wehrheim’s seats on the board will be up for a vote come November, with the incumbents facing off against Inzerillo and Democrat Larry Vetter, who announced his candidacy earlier this year. The winners will join incumbents not up for re-election, Supervisor Pat Vecchio, Councilman Tom McCarthy and Councilwoman Lynne Nowick — all Republicans.
